1981 Honda 9.9, 4 stroke o/b, Idle problem
I have a mid-80''s 7.5 Honda, and two observations I''ve made:
1> It doesn''t like bad gas. Even a small amount of water makes it cranky.
2> This year, I found the rivets in the ignition/cam timing pulley had worn. The pulley is the small one driven by the belt. Since replacing it, the motor runs/idles much better, and is less noisy.
